Customization Process: What You Provide, We Customize

Adhering to a customer-oriented customization concept, you only need to provide us with the following key parameters. Our professional R&D and engineering team with rich explosion-proof equipment experience will design and configure the most suitable explosion-proof refrigerated air dryer for you, ensuring perfect integration with your production system and full compliance with on-site safety requirements:

• Compressed air handling capacity (Nm³/min or CFM), inlet pressure and inlet temperature.

• Required pressure dew point (from 2℃ to -40℃, or lower according to your special requirements).

• Explosion-proof grade requirements (such as Ex d IIB T3, Ex ia IIC T4, etc.) and on-site hazardous area classification (Zone 1, Zone 2, etc.).

• Working environment conditions (ambient temperature, humidity, installation space, dust concentration and other special requirements).

• Special industry standards or certification requirements (such as CE, ASME, ATEX, IECEx explosion-proof certification).

• Other special needs (such as cooling method, control system type, pipeline interface size, installation mode and maintenance requirements).

Optional Materials & Accessories

To ensure the explosion-proof performance, durability, corrosion resistance and high efficiency of the equipment, we select high-quality explosion-proof materials and accessories that meet international standards, supporting you to choose flexibly according to your on-site environment, industry characteristics and budget:

Optional Materials
